Abstract

An engine disabler spray system allows a first chase vehicle to disable a second fleeing vehicle by spraying a fire suppressant agent from the first vehicle at the second vehicle wherein the fire suppressant agent is sucked through the air intake of the second vehicle'"'"'s engine and once the fire suppressant agent enters the engine, the engine is robbed of oxygen and ceases thereby. The fire suppressant agent is stored within a tank located within the trunk of the first vehicle and is discharged through nozzles located on the back of the first vehicle. The nozzles may be directionally controlled for optimum targeted spraying at the second vehicle.

Claims

1. An engine disabler for disabling an engine of a vehicle being pursued comprising:

a passenger vehicle having a front that is a forward region of the vehicle whenever the vehicle is traveling in a forward or drive manner and a rear and a cargo area in the rear, the vehicle having a at least one body panel;

a tank disposed within the cargo area having a liquid fire suppressant agent stored therein;

a discharge nozzle fluid flow connected with the tank and protruding through the at least one body panel located at the rear of the vehicle;

wherein the fire suppressant agent is pumped from the tank and through the discharge nozzle and directed at an air intake of the engine of the vehicle being pursued, such that when the air intake of the engine sucks the fire suppressant agent, the engine is thereby disabled.

2. The engine disabler as in claim 1 wherein the nozzle is capable of being directionally controlled.

3. The engine disabler as in claim 2 further comprising a directional control switch for directionally controlling the nozzle.

4. The engine disabler as in claim 1 further comprising a servo motor mechanically linked to the nozzle for directionally controlling the nozzle.

5. The engine disabler as in claim 4 further comprising a directional control switch for directionally controlling the nozzle.

6. The engine disabler as in claim 1 wherein the fire suppressant agent is FE-36 clean agent fire extinguishant.

7. The engine disabler as in claim 1 wherein the fire suppressant agent is selected from the group consisting of:

Halon 1211, Halon 1301, IG-541, HFC-227ea, HFC-2 (FE13), HCFC Blend A, Carbon Dioxide, high expansion foam, protein foam, AFFF, microbial containing foam, Carbon Tetrachloride, dry powder extinguishant, and wet chemical extinguishant.

8. A disabler for use within a first vehicle having a front that is a forward region of the vehicle whenever the vehicle is traveling in a forward or drive manner and a rear and a cargo area in the rear, the vehicle having a at least one body panel for disabling the engine of a second vehicle, the second vehicle having an air intake air flow connected with the engine, comprising:

a tank stored within the first vehicle, the tank having a liquid fire suppressant agent stored therein;

a discharge nozzle fluid flow connected with the tank, the discharge nozzle protruding, through a body panel located at the rear of the first vehicle; and

wherein the fire suppressant agent is pumped from the tank and through the discharge nozzle and directed at an air intake of the engine of the second vehicle, such that when the air intake of the engine sucks the fire suppressant agent, the engine is thereby disabled.

9. The disabler as in claim 8 wherein the nozzle is capable of being directionally controlled.

10. The disabler as in claim 9 further comprising a directional control switch for directionally controlling the nozzle.

11. The disabler as in claim 10 wherein the directional control switch is mounted on a dashboard of the first vehicle.

12. The disabler as in claim 8 further comprising a servo motor mechanically linked to the nozzle for directionally controlling the nozzle.

13. The disabler as in claim 12 further comprising a directional control switch for directionally controlling the nozzle.

14. The disabler as in claim 13 wherein the directional control switch is mounted on a dashboard of the first vehicle.

15. The disabler as in claim 8 wherein the fire suppressant agent is FE-36 clean agent fire extinguishant.

16. The disabler as in claim 8 wherein the fire suppressant agent is selected from the group consisting of:

Halon 1211, Halon 1301, IG-541, HFC-227ea, HFC-2 (FE13), HCFC Blend A, Carbon Dioxide, high expansion foam, protein foam, AFFF, microbial containing foam, Carbon Tetrachloride, dry powder extinguishant, and wet chemical extinguishant.

17. The disabler as in claim 8 wherein the tank is located within a trunk of the first vehicle.

18. The disabler as in claim 8 wherein the nozzle is disposed within a rear bumper of the first vehicle.
